So, how does a large company like Cheddite screw up that badly?

I still have a few flats of that load in stock and all the boxes wear the CIP certification.

My gut feeling is that they are mild loads. I've seen no signs of over pressure, and I've used perhaps a dozen flats of them.

For a steel head shell they extract easily and show no primer signs of high pressure whatever.

My BS indicator is wiggling on this 'independent' testing.

I have an honest interest in this subject Drew, I'm not discounting your second hand information but it does not add up in my opinion.
